Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 112; Anal spines: 1; Anal soft rays: 9 - 10. Distinguished by the following characteristics: first dorsal fin spines VII; completely united pelvic fins; scales only on posterior section of the trunk; four modified basicaudal scales at the base of the caudal fin; light to dark brown body color with faint internal bars visible on lighter specimens; 2-4 enlarged re-curved canines in each jaw that project out of the mouth, point out and up in the upper jaw, down and back on the lower jaw (Ref. 92840).

Biology     Glossary (e.g. epibenthic)

Found in association with large barrel sponges, generally along outside hiding in crevices, also sometimes within the sponge tubules (Ref. 92840).

Estimates based on models

Preferred temperature (Ref. 123201): 24.4 - 28.2, mean 27.3 °C (based on 599 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 380 [164, 1,300] mg/100g; Iron = 1.9 [0.8, 4.2] mg/100g; Protein = 18.1 [15.9, 20.0] %; Omega3 = 0.173 [0.054, 0.544] g/100g; Selenium = 39.5 [11.6, 111.7] μg/100g; VitaminA = 92.7 [17.8, 468.6] μg/100g; Zinc = 4.63 [2.46, 7.75] mg/100g (wet weight);
